Best Floor Box and Faceplate for Ethernet for Clean, Hidden Power and Data
A floor box and faceplate for ethernet solves a specific problem: getting network and power to the middle of a room without cables taped across the floor. This roundup covers five recessed boxes that range from a simple round power-and-data unit to a full steel floor kit, and it is written for three kinds of buyers — homeowners finishing a basement or living room, office and conference-room installers, and anyone retrofitting a wood, carpet, or tile floor. The overview table below shows each pick’s key spec, best use, and price tier, so the right one is usually obvious within a minute.
Overview of the Picks

1. Recessed Power and Data Round Floor Box, Flush Mounted with Low-Voltage Keystone (1, Black)
Type: Round recessed floor box, flush mount
Power: 20 Amp, 125V receptacle
Data: Low-voltage keystone opening
Finish: Black
Quantity: 1 box
Best for: Budget power-plus-ethernet drop
This is the simplest way into the category: a round, flush-mounted box that pairs a 20-amp receptacle with a low-voltage keystone slot for an ethernet jack. The round lid sits close to the floor surface, so it disappears into a living room or home office rather than reading as hardware. The 20-amp rating gives it headroom over a standard 15-amp circuit, which matters if the outlet will feed a space heater, vacuum, or desktop rig alongside a network run.
It suits DIYers and budget-conscious homeowners who need one data drop and one power outlet in the same spot. The black finish blends into dark flooring and reads as neutral in most rooms.
Trade-off: A single keystone opening limits the box to one data run, so anyone planning multiple ethernet drops should look at the multi-port picks instead.
2. 2 LAN, 4.8A USB Chargers, HDMI Recessed Flat Hidden Floor Outlet Box (Silver)
Type: Recessed flat floor outlet box
Data: 2 LAN ports
A/V: HDMI pass-through
Charging: 4.8A USB chargers
Finish: Silver
Best for: Conference tables and media rooms
This box is built for the meeting-room scenario: two ethernet ports, an HDMI feed, and USB charging in one flush silver plate. The HDMI pass-through is the standout — it lets a projector or display cable run under the floor instead of across it, which is exactly the mess conference rooms and home theaters fight. The flat lid keeps the box low-profile under a table or in a media room floor.
It fits office managers, AV installers, and home-theater owners who need video and network at the same floor location. The silver finish suits light floors and modern furniture.
Trade-off: The HDMI and USB features push the price above a plain power-and-data box, so buyers who only need ethernet and a receptacle pay for capability they will not use.
3. Floor Electrical Outlet Cover Box with USB-C, USB-A, 2 RJ45 Data Ports, and 3 AC Receptacles
Type: Recessed hidden floor outlet box
Data: 2 RJ45 ports
USB: 1 PD 20W Type-C, 1 USB-A
Power: 2 × 20A and 1 × 15A receptacles
Best for: Dense desk and workstation setups
This is the most loaded box in the roundup: two RJ45 data ports, a 20W USB-C PD port, a USB-A port, and three AC receptacles packed into one recessed plate. The 20W Type-C output is enough to fast-charge a phone or top off a laptop, and the mix of 20-amp and 15-amp receptacles covers both heavy and light loads. It is aimed at a workstation or shared desk where laptops, monitors, and wired network all land in one place.
It suits home-office builders, co-working setups, and anyone who wants to stop juggling power strips. The port count means one floor cutout replaces a wall of adapters.
Trade-off: All that connectivity crowds the plate, and the box demands a deeper floor cavity and careful cable dressing — a tight retrofit may not have the room.
4. RACO 1-Gang Tamper-Resistant Floor Outlet Kit for Wood, Carpet, and Tile
Type: 1-gang floor box kit, recessed
Cutout: 3-9/16 x 4-1/8 in.
Device: Duplex 15A tamper-resistant
Construction: Steel box
Listing: UL and CSA
Finish: Nickel
Best for: Code-conscious retrofits in wood, carpet, or tile
This kit is the traditional electrical-aisle answer: a steel 1-gang box with a tamper-resistant duplex receptacle, listed to UL and CSA, and sized for a specific cutout in wood, carpet, or tile. The tamper-resistant shutters matter in homes with children, and the steel construction is the sturdiest housing here. The stated cutout dimensions let a buyer check fit before cutting.
It suits homeowners and contractors who want a proven, code-friendly floor outlet and are comfortable cutting an exact opening. The nickel finish is understated in most floors.
Trade-off: The kit is power-only — no keystone or RJ45 opening — so ethernet requires a separate low-voltage pass-through or a different box.
5. Arlington FLBR5420MB Recessed Power and Data Round Floor Box (Brass)
Type: Recessed round floor box
Function: Power and data
Finish: Brass
Brand: Arlington
Best for: Visible floors where finish matters
Arlington FLBR5420MB Recessed Power and Data Round Floor Box (Brass)
The Arlington is the finish-forward pick: a round recessed power-and-data box in brass, from a brand known for floor-box hardware. The brass ring reads as a deliberate design detail rather than a utility cover, which matters in hardwood, tile, and other floors where the box stays visible. It handles both power and data in one round footprint.
It suits remodelers and homeowners in higher-end spaces who want the floor box to look intentional. The brand name and finish justify the premium tier.
Trade-off: The premium price buys finish and brand, not extra ports — budget-minded buyers get the same power-plus-data function for far less.
Before You Buy
- Cutout size: Match the box to the opening the floor can take; the RACO kit states its cutout, and round boxes need a hole saw of the right diameter.
- Port count: Count ethernet runs first — one keystone is enough for a single drop, while two RJ45 ports cover a desk plus a printer or access point.
- Power rating: A 20-amp receptacle handles heavier loads than a 15-amp duplex; match the rating to what will plug in.
- Floor material: Wood, carpet, and tile each need different cutting and sealing care, and the RACO kit is explicitly rated for all three.
- Listing and safety: Tamper-resistant shutters and UL/CSA listing matter in homes with children and in any inspected install.
- Depth and drainage: Confirm the cavity depth before cutting, and never place a floor box where standing water can collect.
- Finish: Black, silver, nickel, and brass each suit different floors — pick the one that disappears or complements.
Frequently Asked Questions
-
What is a floor box and faceplate for ethernet used for?
It puts an ethernet jack and often a power receptacle flush in the floor, so network and power reach the middle of a room without cables crossing the floor. -
Can any of these boxes handle both power and data?
Yes — four of the five combine AC receptacles with data ports, while the RACO kit is a power-only floor outlet that needs a separate low-voltage path for ethernet. -
How many ethernet ports are enough?
One keystone suits a single device; two RJ45 ports cover a desk plus a second device like a printer or access point. -
Do these boxes work in carpet, wood, and tile?
The RACO kit is explicitly rated for all three, and round boxes generally install in any of them once the correct circular cutout is made. -
Why does one box cost so much more?
The Arlington’s brass finish and brand name carry a premium, while the black round box delivers the same power-plus-data role at a budget tier. -
Is a tamper-resistant receptacle necessary?
It is the safer choice in homes with children, and the RACO kit includes one along with UL and CSA listing.
Bottom Line
For most buyers, the Recessed Power and Data Round Floor Box in black is the fastest way to add one ethernet drop and one 20-amp outlet without overspending — it is the budget pick that covers the core job. Buyers who need multiple data runs, HDMI, or USB charging should step up to the loaded multi-port box, and anyone in a visible hardwood or tile floor should consider the brass Arlington for the finish.
